Description

Technical Field

[0001] This invention relates to the field of computerized knitting technology, and in particular to a high-precision cam setter and circular knitting machine. Background Technology

[0002] In the conventional design concept of circular knitting machines, the movement trajectory of all knitting needles needs to have an adjustable translation range according to the different requirements of the fabric structure. The movement trajectory of the knitting needles is controlled by the triangular curve groove on the cam. The cam itself is fixed on the slider, and the specific position of the cam is controlled by the up and down movement of the slider through the cam seat, thereby adjusting the movement trajectory of the knitting needles. This adjustment requires both high adjustment accuracy of the cam seat and a large adjustment range of the cam seat.

[0003] Currently, there are two main methods for adjusting sliders in related equipment both domestically and internationally:

[0004] Archimedes' groove adjustment scheme: It mainly consists of a slider with a connecting pin, a return spring for resetting the slider, an adjustment knob with an Archimedes' groove engraved on its end face, and a position display panel fixed on the adjustment knob; the groove on the adjustment knob engages with the connecting pin on the slider, and the slider can be moved up and down by rotating the adjustment knob.

[0005] The screw bevel adjustment scheme mainly consists of a slider machined with a 45-degree bevel, a return spring to reset the slider, a bolt with a 90-degree taper at the end face, and an adjustment knob with position lines engraved on its surface. The bolt contacts the 45-degree bevel surface of the slider. The rotation of the adjustment knob drives the bolt to rotate synchronously, and at the same time, the bolt moves back and forth. The 90-degree taper surface at the front end of the bolt rubs against the 45-degree bevel surface of the slider, thereby realizing the up and down movement of the slider.

[0006] However, the aforementioned Archimedes spiral groove adjustment scheme is limited by the strength and volume of its own metal material. Although its adjustment range can meet the required standard, its adjustment accuracy is far from meeting the requirements. The overall screw inclined plane adjustment scheme can meet the required standard in terms of adjustment accuracy, but its adjustment range is far from meeting the requirements. Therefore, it is very important to find a way to make up for the shortcomings of the above two adjustment schemes so that both the adjustment accuracy and adjustment range meet the usage standards.

[0007] It should be noted that the information disclosed in this background section is intended only to enhance the understanding of the overall background of the present invention, and should not be construed as an admission or in any way implying that the information constitutes prior art known to those skilled in the art. Summary of the Invention

[0008] To address the problem that existing adjustable slider solutions mentioned in the background art all suffer from defects in adjustment accuracy or adjustment range, this invention proposes a high-precision triangular base, which includes a base, an adjustment mechanism, a slider, and a position indicator mechanism.

[0009] The adjustment mechanism is movably mounted on the base;

[0010] The slider is movably mounted on the base, and the slider is movably connected to the adjustment structure. A triangle is fixed on the slider, and a triangular curve groove is provided on the triangle.

[0011] The position indicator mechanism is movably disposed on the side of the base away from the slider. The position indicator mechanism includes a first dial and a second dial. The first dial and the second dial are respectively sleeved on the adjustment mechanism. The adjustment mechanism can drive the first dial to rotate and can indirectly drive the second dial to rotate through a speed reduction component.

[0012] Furthermore, the first dial is located on the second dial, and the first dial and the second dial are respectively engraved with a first indicator line and a second indicator line, and the precision of the first indicator line is higher than that of the second indicator line.

[0013] Furthermore, the adjustment mechanism includes an adjustment knob and an adjustment bolt, one end of the adjustment knob is movably connected to the indication mechanism, and the other end of the adjustment knob is movably connected to the adjustment bolt;

[0014] The adjustment knob has a keyway facing the adjustment bolt. One end of the adjustment bolt is located in the keyway and is movably connected to the keyway. The other end of the adjustment bolt is movably connected to the slider. The outer circumferential surface of the adjustment bolt is threaded to the base.

[0015] Furthermore, the end of the adjusting bolt away from the adjusting knob is provided with a cone, and the slider is provided with an angled surface on the side facing the adjusting bolt, and the cone is slidably connected to the angled surface.

[0016] Furthermore, the adjustment knob is provided with an eccentric part, which is connected to the deceleration assembly, and the deceleration assembly is connected to the second dial.

[0017] Furthermore, the reduction assembly is a swivel pin gear, comprising an outer gear disk and an inner gear disk. The outer gear disk is fixed on the base, the inner gear disk is connected to the eccentric part for transmission, the inner gear disk is movably connected to the second scale disk, and the outer gear disk meshes with the inner gear disk.

[0018] Furthermore, the number of teeth on the outer toothed disc differs from the number of teeth on the inner toothed disc by one tooth.

[0019] Furthermore, the high-precision triangular base also includes a connecting pin, one end of which is movably connected to a first connecting groove on the internal gear plate, and the other end of which is movably connected to a second connecting groove on the second scale plate.

[0020] Furthermore, the bottom of the base is provided with fixing holes.

[0021] The present invention also provides a circular knitting machine comprising a plurality of high-precision cam seats as described in any one of the above claims;

[0022] Multiple high-precision triangular seats are arranged sequentially on the circular knitting machine.

[0023] Based on the above, the high-precision triangular base provided by the present invention completely breaks the inherent understanding in the prior art that "one adjustment knob can only correspond to one dial for reading". By simultaneously setting a first dial and a second dial on the adjustment knob, and establishing an indirect transmission relationship between the second dial and the adjustment knob through a reduction gear, the first dial and the second dial are proportionally rotated in the axial rotation direction. This allows the first dial to intuitively display the fine adjustment data of the adjustment knob, while the second dial, in cooperation with the reduction gear, displays a wide range of adjustment data. By combining the coarse and fine data, high-precision positioning of the slider is obtained within a large stroke range.

[0024] Other features and beneficial effects of the present invention will be set forth in the following description, and some of these features and beneficial effects may be learned by practicing the invention. The objectives and other beneficial effects of the invention can be achieved and obtained through the structures specifically pointed out in the description and other contents.

[0043] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. The technical features designed in the different embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.

[0044] In the description of this invention, it should be understood that the terms "center," "lateral," "upper," "lower," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," and "outer," etc., indicating orientation or positional relationships based on the orientation or positional relationships shown in the accompanying drawings, are only for the convenience of describing the invention and simplifying the description, and do not indicate or imply that the device or component referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of the invention. Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this invention, unless otherwise stated, "a plurality of" means two or more. Additionally, the term "comprising" and any variations thereof mean "at least comprising."

[0045] To facilitate a full understanding of the improvements of this invention, we will first provide a detailed explanation of the two adjustment schemes in the prior art. The Archimedes spiral groove adjustment scheme has been gradually phased out of the market because its adjustment accuracy is far from meeting the requirements. Here, we will mainly describe the screw inclined plane adjustment scheme.

[0046] Please see Figure 1 , Figure 1 The diagram shows the structure of the triangular seat for the existing screw bevel adjustment scheme. As shown in the figure, the triangular seat mainly consists of a slider with a 45° bevel surface, a return spring for resetting the slider, a bolt with a 90° taper on the end face, and an adjustment knob with scale lines engraved on the exterior.

[0047] When in operation, one end of the bolt's taper contacts the 45° angled surface of the slider. By rotating the adjustment knob, the bolt rotates synchronously. At this time, due to the threaded connection between the bolt and the base, the bolt moves forward or backward, and the 90° taper surface at the front end of the bolt rubs against the 45° angled surface of the slider.

[0048] When the bolt moves forward, the friction point between the bolt's conical surface and the slider's angled surface moves upward, pressing the slider downward; when the bolt moves backward, the friction point between the bolt's conical surface and the slider's angled surface moves downward, and the slider moves upward under the action of the return spring, thus realizing the up-and-down movement of the slider, which in turn drives the triangle to move up and down. Figure 2 As shown, Figure 2 This is a schematic diagram of the triangular curve groove. When the triangle moves up or down, the triangular curve groove moves up or down accordingly, thereby changing the needle trajectory.

[0049] The advantage of this structure is that the scale display on the adjustment knob is usually engraved with 50 small divisions, each corresponding to an adjustment range of 0.015 mm. Its adjustment display accuracy basically meets the usage requirements.

[0050] Its disadvantage is that the adjustable range of the corresponding slider is only 0.75mm for each full rotation of the adjustment knob, while the required adjustment range in actual use needs to exceed 3mm. Therefore, its effective adjustment range is far from meeting the requirements. Although rotating it multiple times can increase its adjustable range, it is impossible to know exactly how many full rotations the adjustment knob has made, and when the required adjustment range is half a full rotation, accurate readings cannot be obtained.

[0051] To address the deficiencies and shortcomings of the existing technology, or to achieve at least one or more of the aforementioned advantages, an embodiment of the present invention provides a high-precision triangular mount. Please refer to... Figure 3 and Figure 4 , Figure 3 This is a schematic diagram of the structure of a high-precision triangular bracket provided in an embodiment of the present invention; Figure 4 yes Figure 3 A schematic diagram of the cross-sectional structure at point AA. As shown in the figure, the high-precision triangular base includes a base 10, an adjustment mechanism 20, a slider 30, and a positioning mechanism 50;

[0052] The adjustment mechanism 20 is movably mounted on the base 10. Specifically, as shown... Figure 5 and Figure 6 As shown, the adjustment mechanism 20 includes an adjustment knob 21 and an adjustment bolt 22. One end of the adjustment knob 21 is movably connected to the indicator mechanism 50, and the other end of the adjustment knob 21 is movably connected to the adjustment bolt 22. The adjustment knob 21 is provided with a keyway 211, and the keyway 211 faces the adjustment bolt 22. One end of the adjustment bolt 22 is located in the keyway 211 and is movably connected to the keyway 211. The other end of the adjustment bolt 22 is movably connected to the slider 30, and the outer peripheral surface of the adjustment bolt 22 is threadedly connected to the base 10.

[0053] Understandably, in order for the adjustment knob 21 to transmit torque in the axial rotation direction between itself and the adjustment bolt, the keyway 211 is non-circular in shape.

[0054] The slider 30 is movably mounted on the base 10. Specifically, the back of the base 10 is provided with a slider groove (not shown in the figure). The slider 30 can move up and down in the slider groove. The slider 30 is movably connected to the adjustment structure 20. A triangle 40 is fixed on the slider 30. The triangle 40 is provided with a triangular curve groove 41 for changing the movement trajectory of the knitting needle.

[0055] In practice, the adjusting knob 21 and the adjusting bolt 22 are assembled in the base 10. The end of the adjusting knob 21 furthest from the keyway 211 has an adjusting groove 212. By inserting a wrench into the adjusting groove 212, the adjusting knob 21 can be rotated. The keyway 211 is elliptical. One end of the adjusting bolt 22 is non-circular and extends into the keyway 211, engaging with it in a transmission relationship, thereby causing the adjusting bolt 22 to rotate. The outer circumferential surface of the adjusting bolt 22 is threaded, and the adjusting bolt 22 is threadedly connected to the base 10. When the adjusting bolt rotates, it establishes a transmission relationship with the base 10, causing the adjusting bolt 22 to move forward or backward.

[0056] Based on the above, the end of the adjusting bolt 22 away from the adjusting knob 21 is provided with a cone 221, and the slider 30 is provided with an angled surface 31 on the side facing the adjusting bolt 22. The cone 221 and the angled surface 31 are slidably connected.

[0057] Specifically, the cone 221 has a 90° cone shape and the top of the cone 221 has a rounded corner design.

[0058] When adjustment is made, the adjustment knob 21 drives the adjustment bolt 22 to rotate, establishing a transmission relationship between the adjustment bolt 22 and the base 10, causing the adjustment bolt 22 to move forward or backward. When the adjustment bolt 22 moves forward (i.e., towards the slider 30), the cone 221 presses forward against the beveled surface 31, causing the slider 30 to be pressed downward, which in turn drives the cam 40 to move downward. The cam groove 41 on the cam 40 moves accordingly, thereby changing the movement trajectory of the knitting needle.

[0059] When the adjusting bolt 22 moves backward (i.e. towards the adjusting knob 21), the beveled surface 31 is no longer squeezed by the cone 221, and the slider 30 moves upward under the action of the return spring 60, which drives the triangle 40 to move upward. The triangle groove 41 on the triangle 40 moves accordingly, thereby changing the movement trajectory of the knitting needle.

[0060] It should be noted that the adjusting knob 21 and the adjusting bolt 22 only transmit rotational torque, not forward or backward pushing force. That is, the axial rotation (axial direction of the adjusting knob 21) of the adjusting knob 21 and the adjusting bolt 22 is synchronized, but their axial forward and backward movements are independent and do not affect each other. Therefore, the diameter of the adjusting bolt 22 does not need to be limited by the diameter of the adjusting knob 21. Increasing the diameter of the adjusting bolt 22 increases the contact area between the cone 221 and the beveled surface 31, which reduces the frictional pressure between them during adjustment and prevents the cone 221 from scratching the beveled surface 31, thus avoiding loss of accuracy.

[0061] Specifically, when the adjusting knob 21 drives the adjusting bolt 22 to rotate, the position of the adjusting knob 21 itself remains unchanged in the axial direction. Due to the transmission relationship established between the adjusting bolt 22 and the threaded connection with the base 10, the adjusting bolt 22 moves axially forward or backward.

[0062] In existing technologies, the bolts are designed as a single piece, and the bolt diameter is limited by the diameter of the adjustment knob, which in turn is limited by the overall height of the triangular base. This results in the bolt diameter being very small, with a small contact area between the cone and the oblique surface of the slider, resulting in high pressure and easy scratches on the oblique surface, leading to a loss of precision.

[0063] Please combine Figure 4 See Figure 7 As shown in the figure, the position indicator 50 is movably disposed on the side of the base 10 away from the slider 30. The position indicator 50 includes a first dial 51 and a second dial 52. The first dial 51 and the second dial 52 are respectively sleeved on the adjustment knob 21. The adjustment knob 21 can drive the first dial 51 to rotate synchronously. The adjustment knob 21 can indirectly drive the second dial 52 to rotate through the reduction gear 80.

[0064] Specifically, such as Figure 8 As shown, the adjusting knob 21 has an eccentric part 70, which is connected to the reduction assembly 80. The reduction assembly 80 is a swivel pin gear, which includes an outer gear plate 81 and an inner gear plate 82. The outer gear plate 81 is fixed to the base 10 by a fastener 90. The inner gear plate 82 is connected to the eccentric part 70 for transmission and is movably connected to the second scale plate 52. The outer gear plate 81 and the inner gear plate 82 mesh with each other.

[0065] In practice, the outer gear disk 81 is provided with a pair of symmetrical disc lugs 811, which are fixed to the base 10 by fasteners 90, thereby fixing the outer gear disk 81 to the base 10. The inner gear disk 82 is sleeved on the eccentric part 70.

[0066] When the adjustment knob 21 is rotated, it drives the eccentric part 70 to rotate. The eccentric part 70 transmits eccentric force to the internal gear disk 82, so that the internal gear disk 82 cooperates with the external gear disk 81 to reduce the speed of the oscillating needle (the principle of conventional oscillating needle reduction gear will not be described here). At this time, since the internal gear disk 82 is connected to the second scale disk 52, it will drive the second scale disk 52 to rotate synchronously, thereby establishing a proportional rotation relationship between the first scale disk 51 and the second scale disk 52 in the axial direction (the axial direction of the adjustment knob 21).

[0067] Preferably, the number of teeth on the outer gear disk 81 differs from the number of teeth on the inner gear disk 82 by one tooth. For example, the outer gear disk 81 has 12 teeth and the inner gear disk 82 has 11 teeth, which can be set according to the specific adjustment range required.

[0068] For ease of understanding, the outer gear disk 81 described in this embodiment has 10 teeth, and the inner gear disk 82 has 9 teeth. That is, when the inner gear disk 82 rotates one revolution, the outer gear disk 81 rotates one-ninth of a revolution.

[0069] Based on this, the first dial 51 is engraved with the first position line 511, and the second dial 52 is engraved with the second position line 521.

[0070] In practice, the first indicator line 511 is a scale line divided into 50 equal parts. The displacement of the slider 30 represented by one division is 0.01 mm. When the first scale 51 rotates one revolution, the displacement of the slider 30 is 0.5 mm.

[0071] The second indicator line 521 is a scale line divided into 9 equal parts. The displacement of slider 30 represented by one division is 0.5MM. When the second scale 52 rotates one full circle, the displacement of slider 30 is 4.5MM.

[0072] When the adjustment knob 21 is rotated, the first scale 51 rotates synchronously with the adjustment knob 21. That is, when the adjustment knob 21 rotates one revolution, the first scale 51 also rotates one revolution synchronously. At this time, the second scale 52 rotates one-ninth of a revolution, and the displacement of the corresponding slider 30 is 0.5 mm.

[0073] If a large range of adjustments is required, the adjustment knob 21 can be rotated further. Through the proportional rotation relationship between the first dial 51 and the second dial 52 in the axial rotation direction, the first dial 51 can read a fine displacement amount, which is as fine as 0.01MM, while the second dial 52 can read a large range of displacement amounts, so that the displacement amount reaches an ultra-large range of 4.5MM, so as to simultaneously meet the requirements of adjustment accuracy and adjustment range.

[0074] In some preferred embodiments, the high-precision triangular base also includes a connecting pin 100, one end of which is movably connected to a first connecting groove 821 on the internal gear plate 82, and the other end of which is movably connected to a second connecting groove 522 on the second scale plate 52.

[0075] In practice, when the internal gear disk 82 and the external gear disk 81 cooperate to decelerate the oscillating needle, the connecting pin 100 moves in the first connecting groove 821 to eliminate the influence of the displacement generated during the deceleration of the internal gear disk 82 on the second scale 52.

[0076] In some preferred embodiments, the bottom of the base 10 is provided with a fixing hole 110. The high-precision triangular seat is fixed to the circular loom through the bolt fixing hole.

[0077] In some preferred embodiments, the present invention also provides a circular knitting machine comprising a plurality of the aforementioned high-precision cam seats. The plurality of high-precision cam seats are arranged sequentially on the circular knitting machine.

[0078] In summary, the high-precision triangular base provided by this invention completely breaks the conventional understanding that "one adjustment knob can only correspond to one dial for reading" in the prior art. By simultaneously setting a first dial and a second dial on the adjustment knob, and establishing an indirect transmission relationship between the second dial and the adjustment knob through a reduction gear, a proportional rotation relationship between the first dial and the second dial in the axial rotation direction is achieved. This allows the first dial to intuitively display the fine adjustment data of the adjustment knob, while the second dial, in cooperation with the reduction gear, displays a wide range of adjustment data. By combining the coarse and fine data, high-precision positioning of the slider is obtained within a large stroke range.

[0079] Furthermore, those skilled in the art should understand that although many problems exist in the prior art, each embodiment or technical solution of the present invention can be improved in only one or a few aspects, without necessarily solving all the technical problems listed in the prior art or the background art simultaneously. Those skilled in the art should understand that any content not mentioned in a claim should not be construed as a limitation on that claim.

[0080] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, and not to limit them; although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features; and these modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of the present invention.
